10. Presence or history of significant genital, gastrointestinal, liver or kidney disease, or any other condition that is known to interfere with drug absorption, distribution, metabolism or excretion, or known to potentiate or predispose to undesired effects

12. Presence of clinically significant ECG abnormalities at the Screening visit, as defined by the Investigator

13. Known presence or history of thrombophlebitis or any thromboembolic disorders (eg, venous thrombosis, arterial thrombosis), with or without pulmonary embolism

14. Known predisposition for venous or arterial thrombosis, with or without hereditary involvement such as Activated Protein C-resistance (including Factor V Leiden), antithrombin-III deficiency, protein C deficiency, protein S deficiency, hyperhomocysteinemia, and antiphospholipid antibodies (anticardiolipin antibodies, lupus anticoagulant)
